一种针刺无纺布的废边提前切除装置
本技术涉及无纺布生产设备
,尤其是一种针刺无纺布的废边提前切除装置。
技术介绍
针刺无纺布的生产过程主要是:PP粒料经螺杆挤压机挤压到熔融状态,经喷丝板喷出纤维状的长短丝,经过梳理后形成一层纤维网,纤维网通过网带传送给铺网机来回铺网,蓬松的多层纤维网在喂给帘夹持下送入预针刺机进行预针刺加固,形成具备一定的强度、密度和厚度的初级布面,然后再送至主针刺机,通过刺针对纤维网反复进行穿刺,使纤维进行缠结,形成有一定强度和密度的布面,再经过热轧定型并收卷,必要时可在热轧定型工序之后进行烧毛压光处理。上述过程中,铺网后的多层纤维网非常蓬松,其两侧的边沿存在厚薄不均,边缘不齐整的现象,经过预针刺和主针刺后,虽然形成了较为平整的布面,但边缘依然不齐整,经过热轧机定型后需要用切边机构切除两侧的废边,才能进行收卷操作。现有技术中,热轧定型后切除的废边仍然可以回收处理,但由于纤维网经过热轧后变成比较紧密的布面,开松机将这些布面状态的废边重新松解成纤维丝需要耗费很长的时候,电能消耗较大,回收效益不佳,企业往往将其当做废品售卖。如中国专利201610184966.4提供的一种水刺无纺布棉网成型后切边装置,该专利申请是将还没有变成布的纤维网的虚边整齐剪下,重新返回生产线进行重新利用,留给纤维网一个非常整齐的边,减少热压后废边的量,提高成品率。从该申请的说明书记载可知,该切边装置是设置在铺网机之后、预针刺机之前,将蓬松状态的纤维网的虚边切除。该方案虽然在一定程度上减少了废边的量,然而经过该装置切边后的纤维网,经过预针刺和主针刺工序后,由于刺针的穿 ...
